In this page, you can experience authentication through a form that can accommodate passkeys, passwords and identity federation. ## Prerequisites * Chrome desktop 137 or later with `chrome://flags#fedcm-autofill` enabled. ## How to use Put your cursor on the input field (it may take a few seconds to get the identity federation option to appear). Select a password, a passkey or identity federation suggested in the form autofill to sign in, or manually enter a username to continue. If you haven't created an account on this website with identity federation in the past, go to [FedCM active mode](/fedcm-active-mode) or [FedCM passive mode](/fedcm-passive-mode) to create one and come back here. ## How to develop You can enable **FedCM form autofill** by appending `mediation: "conditional"` to the `navigator.credentials.get()` call to an ordinary FedCM authentication invocation. Also, the `input` element must contain `webidentity` within its `autocomplete` attribute. ### Learning resources * [Implement an identity solution with FedCM on the Relying Party side](https://privacysandbox.google.com/cookies/fedcm/implement/relying-party)
